Key result
A 79-year-old man with primary pulmonary MALT lymphoma presenting as a nodular opacity was successfully treated with a thoracoscopic right middle lobectomy and remained recurrence-free at 23 months.

Primary pulmonary MALT lymphoma can present as a nodular opacity and may be successfully treated with surgical resection alone.
May support surgical resection for nodular pulmonary MALT lymphoma; single case leaves optimal management open.
Herein, we describe our experience in treating a case of primary pulmonary mucosa-associated lymphoid tissue lymphoma detected as a nodular opacity. A 79-year-old man was referred to our hospital. Computed tomography showed a nodular opacity measuring 20 mm in diameter with regular margins in segment 5 of the right middle lobe of the lung. Although the bronchoscopic brush cytology result was class III, the patient was tentatively diagnosed with suspected mucosa-associated lymphoid tissue lymphoma. A thoracoscopic right middle lobectomy was performed. The pathological findings showed nodular proliferation of small to medium-sized, mature-appearing atypical lymphoid cells, lymphoepithelial lesions, and vague follicles suggesting follicular colonization in some areas. The patient was diagnosed with low-grade small B-cell lymphoma and mucosa-associated lymphoid tissue lymphoma. He has remained well to date, 23 months after surgery, without evidence of recurrence.

Yoshino et al. (2017) conducted a case report in Primary pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma (n=1). Thoracoscopic right middle lobectomy was evaluated on Recurrence. A 79-year-old man with primary pulmonary MALT lymphoma presenting as a nodular opacity was successfully treated with a thoracoscopic right middle lobectomy and remained recurrence-free at 23 months.
